چکیده مقاله
Based on materials classification, high entropy alloys represent a novel category of advanced and innovative materials that have rapidly garnered significant attention and research interest due to their wide spectrum of properties, characteristics, and potential applications This study investigates the impact of a combined manufacturing process involving vacuum arc melting and disc milling on the characteristics of AlCoCrFeNi high entropy alloy powder, intended for use in laser cladding applications Initially, the alloy was produced via vacuum arc melting and subsequently converted into powder through disc milling To evaluate the microstructure and characterize the powder, analyses were conducted using ICP, XRD, SEM, LPSA The results revealed that the disc milling process successfully transformed the dual phase BCC FCC structure of the as cast alloy into a single phase BCC nanocrystalline structure, featuring a crystallite size of approximately 63 nm and a lattice strain of 0 62% Furthermore, the produced powder exhibited excellent chemical homogeneity and uniform elemental distribution However, the powder particles were non spherical and possessed a broad size distribution ranging from 18 to 111 micrometers
